Build a 3D pipeline scene

Overview

All kinds of pipelines and pipelines on the ground and underground are important infrastructure of the city. It has the characteristics of large scale, wide range, various pipelines, complex spatial distribution, great changes, long formation time and so on. It undertakes the important functions closely related to people's lives, such as information transmission, energy transmission, sewage discharge, and is also the material basis for the survival and development of cities.

With the deepening of China's urbanization process, the traditional two-dimensional management mode has been unable to meet the actual needs of people for the analysis, expression and application of pipe network and pipeline Data Information, and three-dimensional pipeline management has gradually replaced the two-dimensional management mode. The two-dimensional system only has points and lines to represent the pipe network, and the construction cost of the system is not high.

In the 3D pipeline scene, it is necessary to use 3D pipe-point model and pipeline model to show the pipe network system, but the cost of using 3D modeling software to build the model is high. In addition, in 3D pipeline modeling, there is often a problem of poor matching effect between the pipe orifice of the pipe-point model and the pipeline, and the business Attributes need to be re-entered into the Model from the Point and Line Dataset, resulting in the maintenance of two sets of data at the same time and the failure to meet the real-time update requirements.

Based on this, SuperMap has introduced the 3D pipeline full Workflow Management technology, which provides adaptive pipe point symbols based on 2D and 3D integration technology, and can generate 3D Network Dataset from 2D points and Line Dataset. According to the direction of the pipe network and the section of the pipeline, the construction cost of the three-dimensional pipe network scene is greatly reduced while the 3D Scene is rapidly constructed, the display performance of the three-dimensional pipeline and the three-dimensional pipe point is improved, the system resource occupation is reduced, the data bearing capacity is greatly improved, Thereby meeting the display, management and application of a larger and more complex three-dimensional pipe network system.

Composition of 3D pipeline scene

The 3D pipeline scene is usually composed of 3D pipelines and 3D pipe points, including the following elements:

Pipeline: including round pipe, square ditch, pipe block, vertical pipe, etc.;
Pipe points: including feature points, wells and ancillary facilities;
- Characteristic points: including elbow, straight, three-way, four-way, five-way, multi-way, reducer, cap, pipe cap, etc.;
- Wells: including square wells, round wells, well chambers, eccentric wells, rain grates, etc.;
- Auxiliary facilities: including valves, water meters, fire hydrants, control cabinets, transformers, junction boxes, etc.;

Based on the symbolic modeling technology, different elements are used in different ways to achieve rapid construction of 3D pipeline scene, as shown in the following figure of 3D pipeline scene composition and display mode. Usually, line symbols are used to construct 3D pipelines, adaptive pipe point symbols are used to construct 3D pipe points, and some special feature points, wells and ancillary facilities are displayed by Model Symbols.

In addition, Parametric Modeling technology can be used to quickly Generate in Bulk tube well models.

Build a 3D pipeline scene

Based on the symbolic modeling and Parametric Modeling technology, the 3D pipeline scene can be quickly constructed. The main steps and functions include:

This step is mainly to connect the original Piple Line to SuperMap iDesktopX. Currently, SuperMap iDesktopX supports direct access to the original Piple Line in formats such as.shp/.csv/.mdb/.dwg. These data usually include the plane location, buried depth (or elevation), direction, nature, specification, material, construction time and ownership unit of the pipeline.

In order to ensure the correctness of the 3D Build Topology Network and Tube Well Modeling, it is necessary to check whether the original Piple Line accessed has errors and whether the Property Field is complete.

Convert the original 2D tube points and Piple Line into 3D point and line data through the Data Conversion function.

The Tube Well Modeling function supports the construction of tube well models based on the original two-dimensional Piple Line through Parametric Modeling technology, so as to accurately express various complex tube wells.

Build 3D Network Dataset and Custom 3D Network Construction Dataset . Build a 3D Network Dataset with spatial Topology based on 3D Tube Data, 3D Piple Line, or Network Dataset.

Build 3D adaptive tube point symbols, 3D markers, 3D linetype symbols, and save them in a symbol library for reuse.

Use 3D Custom Map to quickly construct 3D pipeline scene.
